A few questions / observations:
Example 1
With go run, the files are copied to a temporary location, so that’s not weird. Printing the executable path for catsay-go shows the following:
$ go run Catsay.go
/tmp/go-build596412124/b001/exe
Usage: catsay <Phrase> <Color (1 to 8)>
Colors: 1 2 3 4 5 6 7 8
Catsay.go
import (
"fmt"
"os"
"path/filepath"
)
func main() {
// print current path
ex, err := os.Executable()
if err != nil {
panic(err)
}
exPath := filepath.Dir(ex)
fmt.Println(exPath)
...
Could this be an issue with the project? Does it build normally?
Example 2
Mason won’t work normally with Nix, so you need to either install the tools you need in your system or add them to neovim:
Cannot install gopls using mason.nvim - #2 by eljamm
However, don’t forget to remove the tools that have already been downloaded by going to the Mason menu, hovering over them, then pressing running X.:MasonUninstallAll
If you want to share your config between NixOS and other distros, you can do something like this:
NeoVim cannot start lsp because clangd is not found - #4 by eljamm
So in NixOS, nvim will use the system/home-manager tools while in other distros, Mason will install the binaries as usual.
Example 3
This works on my machine. What happens when you delete target/ and run cargo run again?
